Abstract
A spray booth for applying a coating to a substrate includes an outer chamber (12) containing a fluid therein having a predetermined first temperature and/or humidity and an inner chamber (14) in fluid communication with the outer chamber (12). The inner chamber (14) contains the fluid therein at a higher predetermined second humidity and/or temperature. The inner chamber (14) includes a fan (42) for recirculating a flow of the fluid at the second predetermined temperature and/or humidity therethrough and filters (34,36,44,46) for removing airborne comtaminants. A temperature and/or humidity control device (58) exhausts a predetermined amount of the fluid from the inner chamber (14) out of the inner (14) and outer chambers (12) said exhausted fluid being essentially free of toxic contaminants, the exhaust of the fluid drawing fluid from the outer chamber (22) into the inner chamber (14) to lower the temperature and/or humidity in the inner chamber (14).
